You have questions. We have answers.
The return on investment from AI-driven mainframe modernization is both immediate and long-term. Organizations typically see reduced operational costs through automation, faster time-to-market for new services, and improved developer productivity. AI tools like generative AI and agentic AI accelerate code conversion, testing, and deployment, cutting modernization timelines by up to 50%. Additionally, unlocking legacy data enables new revenue-generating insights and services. The ROI also includes reduced risk exposure, improved compliance, and enhanced customer experiences, all contributing to sustained business growth.
Kyndryl embeds security and compliance into every phase of our modernization approach. We begin with a readiness assessment that includes a security posture review. We apply encryption, access controls, and AI-powered threat detection tools throughout the process. Our agentic AI capabilities help monitor compliance in real-time, while reinforcement learning continuously improves security protocols based on system behavior. We also align with industry-specific regulations and governance frameworks to ensure modernization efforts meet both internal and external compliance standards.
Kyndryl’s approach to bridging the skills gap is automation and enablement. Generative AI automates documentation, code translation (e.g., COBOL to Java), and test generation, reducing reliance on legacy expertise. Agentic AI and AI-assisted tools help reverse-engineer legacy systems and map application boundaries, making them easier to understand and maintain. At the same time, we support workforce enablement through training programs, upskilling initiatives, and role-specific AI tools that empower developers and IT teams to work confidently in hybrid environments. This ensures continuity while preparing teams for future-ready operations.
